The equipment was development by AO NPP VNIIGIS in cooperation with AO NPF GITAS and OOO NPF VNIIGIS-TZS
Electrical exploration equipment 151 VNIIGIS is designed to study the near-surface geoelectrical structure by near-field time-domain electromagnetic sounding.
Problems to be solved
- detailed stratification of near-surface geoelectrical structure within the depth range 2-1000 m;
- fresh groundwater exploration and prospecting;
- fresh-water complex salinization nature within intense oil recovery zones;
- local geoelectrical objects identification and plotting (for example kimberlite pipes);
- plane-table mapping and geotechnical plotting while ore, coal deposits exploration and prospecting;
- intense oil ingress detection and plotting within the depth range up to 1000 m.
